Aylayl, a lush planet, resided in the Aylayl system within Hutt Space, a region of the galaxy. It was situated along the hyperlane known as the Hollastin Run, a route linking it with Hollastin and Tsyk.
Aylayl's terrain featured expansive forests and jagged mountains. Mining operations on the planet extracted metal ore and minerals, with the labor provided by individuals enslaved by the Hutt species.
The 2009 reference work, The Essential Atlas, co-written by Jason Fry and Daniel Wallace, marked the initial appearance of Aylayl, locating it in grid square S-12.
